The number of unarmed Black civilians killed by police each year is so small that you can fit the entire list of names and details since 2014 (31 total) on a few pages of generously-spaced HTML table rows: https://en.wikipedia.org/wiki/List_of_unarmed_African_Americ.... This is against approximately 10 million arrests per year and some multiple of that in total police encounters. While it's tragic that the count is nonzero, any rational person should be amazed that the incidence is so vanishingly low, given the uncertainty inherent to policing. It's truly remarkable that it isn't much much higher. I couldn't find statistics about police killings of unarmed White people, but I wouldn't be surprised if the number is higher than 31 since 2014.
The only reason you think there is (or was) an epidemic of police shootings of unarmed Black people is because the media has worked very hard to maximally exploit cherrypicked cases to get you to believe that.
Furthermore, Black communities are often strong advocates of retaining or even increasing police presence:
> A Gallup poll conducted from June 23 to July 6 [2020] surveying more than 36,000 U.S. adults found that 61 percent of Black Americans said they'd like police to spend the same amount of time in their community, while 20 percent answered they'd like to see more police, totaling 81 percent. Just 19 percent of those polled said they wanted police to spend less time in their area.
The reason for this is obvious. Persistent socioeconomic inequality has had the same devastating impact within Black communities as it has had everywhere else in the world: increased criminality.
